Every October 19, gin lovers around the world celebrate International Gin and Tonic Day, recognising a cocktail that has remained popular for generations.
The modern celebration is commonly traced to 2010, when Mary Edith Keyburn, a gin and tonic enthusiast, died at the age of 95. According to accounts of the day, her family managed to take her favourite drink to hospital, serving it discreetly in a teacup. Her granddaughter, Jayne Withers, later helped establish the celebration in her memory, with social media spreading it internationally from 2012.
The cocktail's history, however, goes back much further. Its origins are linked to 19th century British India, where tonic water containing quinine was used in efforts to prevent malaria. Gin was added to make the bitter tonic easier to drink. The combination eventually moved beyond its medicinal associations to become a popular social drink. The gin and tonic appeared in print as early as 1868.
For Steven Baguma, Reserve Brand Ambassador at Uganda Breweries Limited, the drink's lasting appeal lies in its simplicity and balance of flavours.
“The gin and tonic is a good example of how you do not have to make a cocktail complicated for it to be enjoyable. The gin brings its botanicals, the tonic provides bitterness and fizz, and the citrus helps lift the flavours,” Baguma explains.
The combination has remained popular even as bartenders experiment with different gins, mixers and garnishes. Its basic ingredients remain familiar, making it an accessible choice for both experienced cocktail drinkers and beginners.
Making a gin and tonic at home
Preparing a gin and tonic does not require professional equipment or a fully stocked bar. Gin, tonic water, ice and a slice of lemon or lime are enough to make the classic cocktail.
“You can make a gin and tonic on your kitchen counter. You do not need a professional bar setup. Pour in your gin, add tonic water and finish with a slice of lemon or lime. The idea is to keep it simple and pay attention to the balance,” Baguma says.
A basic recipe uses 45ml of gin topped with between 100ml and 150ml of tonic water, served over ice and garnished with citrus. The quantities can be adjusted to suit personal taste, while an ordinary drinking glass can be used instead of specialised cocktail equipment.
“The important thing is understanding what you are making. Not every gin tastes the same, and the amount of tonic you use can change the experience. Start with a simple recipe, taste the result and learn what works for you,” he adds.
The choice and amount of ingredients influence the final taste. Gin gets much of its character from juniper and other botanicals, while tonic water adds bitterness and carbonation. Too much tonic can overwhelm the gin, while a citrus garnish can complement its flavours.
Exploring different flavours
Different gins produce different results. A classic London Dry gin, such as Tanqueray, has a strong juniper character that suits the traditional gin and tonic.
Uganda Waragi also reflects the place locally produced spirits occupy in Uganda's drinking culture, showing how the wider category has both international traditions and local expressions.
For Baguma, the best way to explore the cocktail is to start with the classic recipe before trying other garnishes and flavour combinations.
“The gin and tonic leaves room for creativity, but you do not need to add lots of ingredients to make it special. Understand the balance first, then experiment with small changes,” he says.
On International Gin and Tonic Day, the cocktail's appeal goes beyond its history. Its simple preparation, range of flavours and long-standing place in drinking culture have helped it remain a familiar choice in bars and homes around the world.
